FIREMANS MASK.

SPECIFICATION forming part of Letters Patent No. 409,428, dated August20, 1889.

Application filed May 15, 1889.

To all whmn it may concern:

Be it known that I, THOMAS E. RICHET, of Portland, in the county ofMultnomah and State of Oregon, have invented a new and Improved FiremansMask, of which the following is a full, clear, and exact description.

The object of my invention is to provide a mask that will effectuallyafford protection against suffocation from the smoke in a burningbuilding.

The invention consists in the construction and combination of parts, aswill be described hereinafter.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of the mask. Fig. 2 is a central verticalsection, and Fig. 3 is a View in full of a fireman with my mask on.

In the drawings, (t represents the frame with the crown or cap I)fitting close to the head of wearer. The lower part also fits close overthe lower jaw to exclude the smoke and foul air. The mask is held inplace by an elastic band 0 passing behind the ears. The mask is made ofrubber or other flexible material, the face portion being heavier togive it some rigidity. At d there are two apertures, in which areinserted eye-lights e of mica or glass, permitting the wearer to viewhis surroundings. The lights a are. held in the apertures by insertionin the circular grooves f in the face of mask. The mouth front isprovided with flange g, which fits in the annular internal groove 7b inthe shutter '5, the latter being centrally pivoted, so that it may beturned on the mouth front by the finger-piece 7c. The shutter has anopening Z, filled with sponge or other porous ma- Serial in). 310,834.(No model.)

terial, which registers with opening m in mouth front and a semicircularopening 02. The shutter may be turned to bring the opening at in linewith the opening m when it is desired to talk. A flexible pipe 0, whichis connected with the lower part of the mask, drops over the breast anddown the inner side of the leg to within a short distance of the floor,so that the 'air along the floor can-pass up to the inside of mask.

Having thus described my invention,what I claim as new, and desire tosecure by Letters Patent, is

1. The combination, with the body of the mask having a mouth-opening, ofa shutter pivoted to the body and provided with two openings adapted toregister with the mouthopening, one of the said openings being fittedwith porous material, substantially as and for the purpose set forth.

2. The combination, with the body of the mask having the mouth-opening mand provided with the flange g aronndthe said opening, of the pivotedshutter i, having an internal groove to receive the said flange andprovided with the openings Z n, the openinglbeing fitted with porousmaterial, substantially as herein shown and described.

3. The herein-described mask, consisting of the body portion a I),provided with two sightopenings (1, covered with glass or mica e, ainoutlropening m below the sightopenings, an apertured shutter 2',pivoted above the mouth-opening and provided with two openings Z n, theopening Zbeing filled with sponge, and the flexible pipe 0, connected tothe lower part of the mask, as specified.
